Monitoring, simulating, creating HTTP packets

Question

I did some HTTP monitoring with WireShark. Are there more tools like this that allow you to create your own HTTP messsages? Telnet comes to mind

Could be handy to get see how hacker-proof your site is...

Answer 1

Charlse HTTP proxy tool is my favorite. You can manually create HTTP request or edit existing HTTP request. http://www.charlesproxy.com/

The completely free tool is Fiddler which has similar functionalities http://www.fiddlertool.com/fiddler/

Charlse runs on different operating systems, it is on top of java VM. Fiddler runs on windows dot net.

Answer 2

I've found Tamper Data quite useful Firefox plugin to fiddle with HTTP headers and parameters. This is very useful if/when you want to hack your (or someone elses :) ) site.
